Arduino Vibration Switch Module KY-002 Keyes allows detection of shock and vibration.
Specifications
The KY-002 Vibration Switch Module consists of a conductive vibration spring and a 10k resistor, it will react to shock and vibration by closing the circuit.
Operating Voltage
5v
Dimensions
18.5mm x 15mm [0.728in x 0.591in]
Connection Diagram
Connect the Power line (middle) and ground (-) to +5 and GND respectively. Connect signal (S) to pin 3 on the Arduino.

Example Code
The following Arduino sketch produces a shock flasher. Pin 13 (LED) on the Arduino will flash when KY-002 detects movement. Pin 3 is used as input from KY-002.
int Led = 13; // define the LED Pin
int shock = 3 // define the sensor Pin
int val; // define a numeric variable val
void setup () {
pinMode (Led, OUTPUT); // LED pin as output
pinMode (shock, INPUT); // input from KY-002 sensor
}
void loop () {
val = digitalRead (shock); // read the value from KY-002
if (val == HIGH ) {// when sensor detects shock, LED flashes
digitalWrite(Led, LOW);
} else {
digitalWrite (Led, HIGH);
}
}
Hi, first of all, I wanted to thank you for sharing this great site with us. Especially the Fritzing vectors and diagrams.
I detected a small mistake in your Example Code. You just have to switch if == HIGH, then HIGH, else LOW. Here is the corrected sktech code:
int led = 13; //Define the LED pin int shock = 3; //Define the push button pin int val; // Define a numeric variable void setup() { pinMode(led,OUTPUT); pinMode(shock,INPUT); } void loop() { val = digitalRead(shock); // read the value from KY-002 if(val==HIGH) { // when sensor detects shock (HIGH), LED flashes digitalWrite(led,HIGH); } else { digitalWrite(led,LOW); } }
